WILLIAM BENTLEY, OF LETHBRIDGE, CANADA.

SASH-FASTENER.

. SPECIFICATION forming part of Letters Patent No. 532,753, dated January 22, 1895.

Application filed January 9,1894. Serial 110496.257. (N model.)

To a whom iv may concern:

Be it known that I, WILLIAM BENTLEY,

' merchant, of the town of Lethbridge, in the district of Alberta, in the Northwest Terri tory, Canada, have invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to an improved frame and fastener for window sashes and the object of the invention is to so connect the window sash to the frame that it will be perfectly wind and dust proof, will always slide up and down easily no matter whether the weather is wet-or dry, will not'rattle and will be automatically locked when closed and it consists essentially of securingin the frame T-shaped anglebars, which extend around the sides and top of the outer sash and around the bottom and sides of the inner sash andfit into corresponding grooved plates inserted in the grooves in the sides and in the top and bottom of the upper and lower sashes respectively and furthermore in providing a fastening consisting of a spring plunger actuated by suitable handle and cam pin so as to lock or hold the sashes in any desired position, the

whole being constructed and arranged in.

detail as hereinafter more particularly explained.

Figure 1, is a perspective view of a window sash, portions of the side of the frame, angle bars and sash being broken away to exhibit the peculiar construction involved in my invention; Fig. 2, is a perspective view of a portion of the side of the sash showing the construction of my catch. Fig. 3, is a sectional detail showing the manner of locking the window. I j

In the drawings like letters of reference indicate corresponding parts in each figure.

A, is the'head of the sash frame; B, B, the sides, and, O, the sill. The head, A, and one side, B, are broken away in Fig. 1.

B, are T- shaped angle bars, which exten from the sill to the head, to the T-shaped angle bar, A, secured to the .head, A. The tongue of the side angle bars, B, and head angle bar, A, are in the same plane and suitably joined at the corners, so as to present a flush or even surface. These angle bars may be secured to the frame in any suitable manner, as for instance, by: nails or screws passing through openings in the side flanges of the,bar, but I have not deemed it.

necessary to show such means in the present drawings.

D, are the stiles of the upper sash and, E, the rails. The stiles, D, have grooves, (1, cut in the outer sides which grooves extend upwardly through the endot' the top rail, E.

s D, are angle bars T- shaped in cross-sec tion and having a groove,d made through-- out the length of the tongue, (1, of such T- shaped bar. The tongue of the grooved T- shaped angle bar fits within the groove, 61, the angle bars being secured to the side of the stile by their flanges.

I show in Fig. 1, of the drawings, only one sidaof the upper sash but it will of course be understood that the other side is arranged cxactly alike.

e, is a groove made throughout the length of the head rail, E. Within the groove fits the tongue, 6, of the T-shaped angle bar, E, which has a groove, 6, formed throughout the length of the tongue.

The stiles, D, and top and bottom rails, E, of the lower sash have grooved T-shaped angle bars, D, fitted into their sides and a grooved T- shaped angle bar, E, fitted into the bottom rail, similarly, to the grooved T- shaped, angle bars described in reference to the upper sash. Corresponding T-shaped angle bars, B, extending from the head to the sill and along upon the top of the sill, are provided for the lower sash. the side bars fit within the groove, d,-of the T-shaped angle bars, which are fitted into the outer sides of the stiles. The tongue of the bottom angle bar, A, fits within the groove, e, of the bottom angle bar, E, fastened to the bottom rail. F, is the plate of the fastener which is secured in a recess in the stiles. The plate and fastener are shown exaggerated in size in Fig. 1, so as toexhibit their construction clearly.

f, is a spring plate, which is secured at its bottom end in a recess to the plate, F, and at its upper end is provided with a plunger,f, which is threaded, so as to be adjustable within the spring plate f.

f", is a spindle journaled in the lug,f forming part of the plate, F, and having secured at one end the handle, J. The out- The tongues of sash, 'as the case may be, the handle, f is thrown out into the position shown in Fig. 2,

7 so as to change the position of the flat end of the spindle, f, and throw the spring plunger out from the recess b, whereupon the sash may be raised, by pressing the handle, f back into position. The pressure of the plunger,f, against the tongueot the plate will retain the sash in any position in which it may be placed. In raising the sash the handles, f may be raised, and utilized for such purpose.

when the sashes are closed it will be seen that they will be securely locked by the pinnger,f, fitting within the recess, 1).

From this description it will be seen that I provide a simple device by which window sashes may be rendered absolutely dust and wet proof and at the same time obviate any danger of such sashes rattling. It will also be seen that the sash may be readily raised outer sides of the stiles and designed to fit and he adjustable upon the tongues of the side bars, of a spring plunger designed to fit within an annular recess in the tongue of the side bar when the window is closed and means for removing the spring plunger when it is desired to open the window as and for the purpose specified.

2. The combination with the window sash and frame having the grooves formed in the outer sides of the stiles and designed to fit and be adjustable upon the tongues of the side bars, of the annular recess, 1), formed in the tongue of the angle bar, B, the spring plate,f, provided with a plunger, f, and the spindle, f, having the semi-circular end located to the inside of the spring plate,f, at the outer end and a handle, f at the inner end as and for the purpose specified.

WILLIAM BENTLEY.
